Kann, of Guttenberg, Iowa, was 52 when he went diving with two other men at the wreck of the Lakeland, a steamer that sank with a load of still-visible cars in 1924 off Algoma, Wis., about 125 miles northeast of Milwaukee. The shipwreck is a popular destination for divers.

Kann’s body was in Whitefish Bay, a mile east of Whitefish Point in the town of Sevastopol, about 20 miles north of Algoma, officials said.

Kann’s widow, Rose Kann, told the Daily Mail the family felt great relief the body was found but that no memorials were planned.

The Advocate reported that Kann and a dive partner experienced problems while surfacing in 175 feet of water on Sept. 4, 1999.

Kann was last seen when he stopped at the 80-foot mark on a dive line to decompress – a requirement in deep dives to prevent the buildup of harmful nitrogen bubbles in the blood. The partner decompressed at the 40-foot mark. He and a third dive partner, who remained on a boat on the lake’s surface, pulled on the dive line but Kann was not there, according to Advocate reports at the time.

Bottles for decompression and emergency air remained on the line where Kann was last seen.
